Access the slope stability by building a slope 3D model directly in Ansys based on the actual size that is already given in the AutoCAD dwg file under the effect of water and seismic.

The selected scale in that file is 1:1000. The slope has gravel soil underneath the shallow slip surface is present and the bedrock is, further followed by a deep slip surface, having a water level at the bottom. The slope has gravel soil, a shallow slip surface, bedrock, and a deep slip surface enclosed by a closed polyline having vertical slip surface slices passing through the closed polyline. Two profile Deep and shallow calculation parameters are given separately.  After creating the 3D model of slope for ‘deep calculation parameters’ the slope is needed to divide into a total of 23 blocks, and for shallow calculation parameters the slope is needed to divide into 14 blocks or sections or strips which can be done by creating distinct regions in your mesh by applying different meshing techniques. After dividing the model into sections assign the appropriate material properties (cohesion and friction angle) to each section based on the information you have from the table. 

You can do this by selecting each section and specifying its material properties using the Mohr-Coulomb model. Apply boundary conditions including changing water level, and seismic effect. Set up the failure criteria factor of safety. Now perform the analysis for each section separately, by applying the changing water levels, and seismic load if needed in that region. After analysis, review the results for each section to determine the stability parameters. Verify that you have obtained results for 14 different sections or blocks in your analysis output. ANSYS should provide results specific to each section. Compare the stability parameters between the different sections to assess the impact of variations in material properties and conditions on slope stability.
